Weird problem just recently started occurring on my '06 cbr600rr. The coolant temp gauge is jumping around like crazy, upon warm up it raises fairly normally, but jumps up and down ~ 20 degrees, and continues jumping back and forth while riding etc. within 20-40 degree variations every few seconds. Fan still kicks on as normal, but the temp even for a brief second will read as overheating, and the warning light will come on, and then jump back down to normal..
I tried googling for other people having similar symptoms with no luck. Any suggestions? Is there a certain way to check the temp censor etc. with a multi-meter? Possible wiring short? or any shop recomendation? I am in Port Coquitlam. Thanks in advance.
